ROLLER BEARING AND BOXING.

SPECIFICATION forming part of Letters Patent No. 672,659, dated April23, 1901.

Application filed July 31, 1900. Serial No. 25,377. (No model.)

To all whom it may concern:

Be it known that we, WALTER S. WOOD, residing in the city of Kalamazoo,and SAMUEL DOUGLASS, residing in the village of Schoolcraft, in thecounty of Kalamazoo and State of Michigan, citizens of the UnitedStates, have invented certain new and useful Improvements in RollerBearings and Boxings, of which the following is a specification.

This invention relates to improvements in roller-bearin gs.

The objects of this invention are, first, to provide a roller-bearingwhich may be easily applied to shafting which is already in position anduse without the necessity of having to take it down or uncouple it inany manner; second, to provide a roller-bearing which can be cheaplymanufactured and which is elfective in operation and durable inconstruction;

third, to provide a rollerbearing in which the bearing-surface on theends of the rollers is reduced to a minimum, so that the rollers willrun in a vertical or inclined position as well as in the horizontalposition and be pre vented from endwise movement; fourth, to provide ina roller-bearing cheap, effective, and easily-applied means of excludingdust and dirt from the revolving parts and also to assist in retainingthe lubricant used; fifth,

0 to provide in a roller-bearing an improved bushing or casing to retainthe rollers which may be .used with ordinary split or solid types ofboxes, as desired, and, sixth, to provide an improved bushing or casing.

5 Further objects will definitely appear in the detailed description tofollow.

We attain these object of our invention by the devices and meansdescribed in this specification.

4o Theinvention is clearly defined and pointed out in the claims.

Structures embodying our invention are clearlyillustrated in theaccompanying drawings, forming a part of this specification, in

Figure 1 is a transverse sectional elevation through a journal-boxembodying our invention, taken on line 1 1 of Fig. Fig. 2 is atransverse sectional elevation taken on line 2 2 of Fig. 3. Fig. 3 is alongitudinal sectional elevation taken on line 3 3 of Figs. 1

and 2, certain of the parts being shown in full lines. Figs. 4 and 5 aredetail longitudinal sectional views showing slight modifications of theboxing more fully described hereinafter. Fig. 6 is a detail sectionalview of one of the end plates F, taken on line 6 6 of Fig. 2. Fig. 7 isa similar view showing a modified form of the same part. Fig. 8 is adetail perspective view of the shafting-roll- 6o ers and casing for sameassembled in posi-- tion, showing details of construction. Fig. 9

is a detail perspective view of a casing substantially as it is formedbefore placing about the shaft and rollers. Fig. 10 is adetailperspective view of a double casing, being substantially duplicates ofthe casing appearing in Fig. 8 with the joints overlapping, but with thewinding omitted. Fig. 11 is a detail view of the casings as they are cutfrom sheet metal. Fig. 12 is a detail view of a modified form of casingmade of a long narrow strip as it would appear about the rollers andshaft, but with the winding omitted.

In the drawings the sectional views are taken looking in the directionof the little arrows at the ends of the section-lines, and similarletters of reference refer to similar parts throughout the severalviews.

Referring to the lettered parts of the drawings, A is a pillow-block orbase of'an ordinary journal-box, and A is the cap therefor, which issecured to the base A by bolts or screws in the ordinary way.

B is the journal or shafting.

E represents rollers arranged around the shaft within the boxing. Theserollers are of such size and number that there is a slight unoccupiedspace on the circumference of the shaft. 0

O O are double casings outside of the rollers E. These casings are cut,preferably from sheet-steel, substantially in the shape shown in Fig. 11and of proper size. The inner casing is preferably made of spring-steel.5 The outer casing is preferably made of annealed steel, brass, copper,or other suitable material. For convenience in assembling these casingsare preferably passed between bending-rollers and shaped substantiallyas shown in Fig. 9. The meeting edges 6 c of these casings shouldpreferably be a little ers, as shown in Fig. 10, thus insuring a closefit about the rollers. The meeting edges 'of these casings shouldpreferably be diagonal to the line of the shafting and rollers, so as toform no obstruction to the rollers in passing the joint. For conveniencein adjusting the casings in position about the rollers an oifset ornotch e e is made in the meeting edges 6 e, which acts to lock the edgesand hold them in proper relation to each other and prevent any slippingwhich otherwise might occur. This is best; but we are aware that othermeans of locking may be employed. In assembling these casings they aresprung open and placed around the shaft and adjusted about the rollersso that the joints of the two casings Shall come substantially atopposite sides of the shaft, as shown in Fig. 10, when they are verysecurely wound, preferably with annealed-metal ribbon 0, usually braSS;although wire or other suitable material may be used. The mostsatisfaetoryre e n W n n are ob aine b team ii 'the center of the casingand winding on}; to each end and back again to the center, wh n he n s 0m y 's'e'ciu'e y as with a little solder, all 'of which is particularlyillustrated in Fig. 8. It willbe apparent that this manner of windingthe casing aboutthe rollers insures a much closer fit of the casing tothe rollers and shaft than is possible to obtain by boring out thecasing from a solid tube and then forcing the rollers into placeendwise, as isfusually done, when the roller or two will,if a'very tightfitis obtained, make a slight groovein "the shaftor casing, or both,which "would bevery detrimental to the smoothworking of theparts. Whilewe'prefer a double casing in the construction of our improvedroller-bearing, we are aware that for small bearings and light work asingle casingds perfectly practical and effective, while for very largebearings carrying heavy loads two or norecasings or as nany as desiredmay be used,-or twojcas ings may be wound on the rollers and thenanother casing placed outside the winding and that in turn wound on, andsoon.

In Fig. 12 W9 fihbw. a modificationof the casing in which the'sheet'metal is cut of the pr pe Shan t9 a m f h s weu d about the o e s ira ya s own, t s appare t that these casings may bewound in the same manneras the others. i

We haye found that in actual practice with roller-bearings there isatendency for more or less of the rollers to get oi 't of proper alinementwith the shaft and casing, which is due principally to slightinaccuracies in the rollerS}. or casing, which seems difficu ltto ove'ceiile' n manu ur ere ypmd n undue friction of the parts. The closenessith w i h e are a l to fi he a n to therollei's obviates thesedifliculties to a great extent andmaintains the rollers practically intrue alinement. When the rollers are out time of true alinement with theshaft, there is a tendency for them to work endwise or creep and crowdhard against the end hearings or collars which are usually used toretain the rollers in place longitudinally. To obviate this difficultyand reduce the friction of the rollers on the end hearings to a minimum,so that they will work in a vertical or inclined position as well as ina horizontal position, we employ an improved end-bearing annular ring Fat each of the rollers E. The rollers are cut perfectly square at theirends. These end-bearing rings F are slightly beveled on their face nextto the end of the rollers, so that the only point of contact between theend of the roller and the ring is at the periphery of the roll, at whichpoint there is practically no movement or rubbing of the rollers on thering, and consequently no friction. Thus it will be seen that any unduefriction caused by tendency of the rollers to work endwise against thebearing-rings is practically obviated and the rollers'will run asfreewhen used in a vertical as in a horizontal position. Theseend-bearing rings are preferably punched or stamped from sheetsteelhaving a spring temper and of substantially the shape shown in Figs. 2and 6.

For'convenience in placiog the rings on shafting which is already inposition, or when it is not convenient to pass them over the end of thesha firthey may be slit, as'at F in Fig. 2, when they can be easilysprung open and placed on the shaft at any desired point. After havingadjusted the casings about the rollers and theannular end-bearing ringsF on the shaft inproper position in the boxing A A We fill the spacebetween the inside ofthe boxing and the outside of the casing andannular rings F with Babbitt metal D or other suitable metal,substantially as we would babb ittan ordinaryjournal-box. This formscovering arofu nd the casing and loeates the bearing inthe pillow-blockor boxing'in true alinement with thejournal. Other snbst anceswhi chwill readily solidify and become sufficiently hard frloina plastie stateand susceptible of being cast in the mold the same as Babbitt onsimilarmetals may in many cases be used inpl'a ce of Babbitt metal.

This insures a perfect alinement of the jshaft and bearings and a solidand secure support liz 'l v n the boxing. The annular rings F haveportions cut out of their peripheries, as at F,

for the purpose of allowing the babbitt to flowthroug h to the outsideof the rings, so

as to hold them in position and to form the end ofthe bushing or boxing.After the windingof the casing is completed it may be entirely orpartially coated with solder by means of a soldering-iron or othermeans, as.

alsomay the outside of the annular rings F. Then the hot babbitt willadhere or amalgamate with the solder and form practically a solid bushing, which may be removed from the boxing and replaced with perfectaccuracy. This correct position is insured by means of the littleprojecting points D on the babbitt To protect the rollers from dust andother substances which would tend to obstruct their free movement andalso to assist in retaining the oil used in lubricating the rollers, weemploy a ring of felt or other suitable substance G, placed around theshaft at each end of the rollers, just outside the end-bearing rings F,which is held in position by means of spring-rings G, all of which isshown in Fig. 3, the ring of felt and the spring at the left-hand end inthe drawings being shown in section. Set-collars H H on the shaft ateach end of its boxing are for the purpose of preventing longitudinalmovement of the shaft. They are chambered out to fit over the rings Gand G, as shown in Fig. 3.

much cheaper than a cast box.

It is obvious that with the end-bearing rin gs F at each end of thecasing there is formed a practical and efiective oil-reservoir in thebottom thereof which every roller must pass through every ti meit passesaround the shaft, thus insuringcomplete lubrication. The oilis suppliedthrough the oil-cup in the top of the boxing, as shown.

We desire to state that while we have shown and described our inventionin its preferred form we are aware that it may be greatly Varied withoutdeparting from the spirit of our invention. The pillow-block or boxingmay be made of wood in many cases and will be found to answer everypurpose and be The casings G C may be made of drawn-steel tubing and cutopen on one side in any suitable manner, so as to allow the tubing to bewound down tight to the rollers. The features outside of the casingcould be made use of with any other casing, as a casing could be made ofa piece of drawn tubing when the close fit of the easing to the rollerswas not material, and this casing could beplaced on the shafting overthe end.

We desire also to state that While we have shown our device as appliedto bearings for shaftings it may be applied to hubs of loose pulleys,wheels, and axles for vehicles, 850.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is
